what i mean was, user interface for the printer driver, i need a spin control for various edit controls, like one for entering no. of copies to be printed.
afxwin.h is included in my code, the thing is that, my code works without error in xp, using wdk environment.
as i m using(i have to) DDk for 98, so i m facing this problem.

afxcmn.h and afxwin.h are located in the same directory, so if you can successfully include afxwin.h you shouldn't have any problem finding the afxcmn.h file.
Try building without the CSpinButtonCtrl and see if this is the only include problem you have and to verify that you can successfully include the afxwin.h file.
I assume you've included the file by writing...
#include <afxcmn.h> ...and not...
#include "afxcmn.h" ...so the compiler can search the include path instead of assuming the file is located in the project directory.

Yes, I used #include <afxcmn.h>, and i tried without CSpinButtonCtrl in my code, the it gives error for the header file.
I am using afxwin.h since long time back, and i have been using mfc classes like cbutton and cdialog without any hitch.
only after the problem with the CSpinButtonCtrl, i included afxcmn.h. I think, ddk is not having a library which wdk has.
thanks for ur concern...

I have used the below code to determine the Host Name of the local machine in which the application is running. gethostname() function returns SOCKET_ERROR. The same code works fine in another application. Pls tell me why it is not working in my application. Should I change any Project settings.
SOCKADDR_IN sockAddr;
memset(&sockAddr,0,sizeof(sockAddr));
CString rSocketAddress;
LPHOSTENT lphost;
char HostName[80];
if (gethostname(HostName, sizeof(HostName)) == SOCKET_ERROR)
{
AfxMessageBox(WSAGetLastError());
PostQuitMessage(WM_QUIT);
}
//_tcscpy(mInstSess[ind].INSHost,HostName);
m_sInsHost = HostName;
lphost = gethostbyname(HostName);
if (lphost != NULL)
{
sockAddr.sin_addr.s_addr = ((LPIN_ADDR)lphost->h_addr)->s_addr;
rSocketAddress = inet_ntoa(sockAddr.sin_addr);
//strcpy(mInstSess[ind].INSIP,rSocketAddress);
m_sInsIP = rSocketAddress;
}
Thanks in advance

So what does WSAGetLastError() tell you?

It simply printed m in the messagebox
The function returned -1

What? -1?
Here are the error codes and I don't see -1 in it: Windows socket error codes[^]

AfxMessageBox() takes either a string to display, or a resource ID corresponding to a post in the string table as argument.
Since you're passing the return value from WSAGetLastError(), which is an integer value, the AfxMessageBox() function will try to load the string that matches that ID from the string table. Likely that ID does not exist in the string table and the call fails, hence the "-1".
Assign the return value from WSAGetLastError() to a variable and debug your code.

WSAGetLastError() returns an integer and you are passing it on to AfxMessageBox(). Talk about horror.

Make sure that WSAStartup() or AfxSocketInit() has been called successfully before you call any socket winsock functions.

Can anybody help me in finding the number of files in a particular folder.
I am using VS 6.0.
With regards
Deepu.

Do you need to CFileFind Class or FindFirstFile?
|
|
|
|
|
I am using CFileFind
Is that possible by using CFileFind::FindFile and CFile::FindNextFile.
If so can you tell me the procedure.
|
|
|
|
|
This exampl eis on the MSDN.
CFileFind finder;
BOOL bWorking = finder.FindFile(_T("*.*"));
while (bWorking)
{
bWorking = finder.FindNextFile();
TRACE(_T("%s\n"), (LPCTSTR)finder.GetFileName());
}

Hi Hamid and Machael
I came across a strange situvation
If i have to find the files in the "*.*" , it is working.But if i have to find in any other directories i have to append "\\*" to the end of the directory name and finally reduce the the count by 2;
CFileFind finder;
int NoOfFiles = 0;
BOOL bWorking =finder.FindFile( "D:\\Directory\\Subdirectory\\*") ;
while(bWorking)
{
bWorking = finder.FindNextFile();
NoOfFiles++;
}
NoOfFiles-=2;//Now it will give the actual number of files
}
why it so.I got the output but it is strange!!

Most likely because you are counting the current and parent folders. Check out the CFileFind::IsDirectory() method.

yes the first two values is directories.
But even if there are more than 2 directories
for eg e:\dir\subdir\subsubdir..
the first two values are showing only as directories.
still the count should be reduced by 2.

If you are only wanting to count files, then you must exclude those that are directories. If you are wanting to count everything except the current and parent directories, then you must exclude those directories whose name begins with a dot, like:
while (bWorking)
{
bWorking = finder.FindNextFile();
if (! finder.IsDots())
NoOfFiles++;
}

Ah, but filenames can begin with a dot. It's best to check the attributes OR if the filename is nothing but dots.

Of course, and I believe my comment accounted for that.

Which is exactly what IsDirectory() and IsDots() does.

Sorry, misread your comment.

Use FindFirstFile() and FindNextFile() to enumerate the files.
There are articles here on Code Project, there are also Google and MSDN. Search!

Hi there,
I have a CWnd derived class that displays bitmap data in its client area using the BitBlt function of a compatible CDC object.
This works fine in the usual case on one PC.
However, if I run my application on a remote PC using WinXP's Remote Desktop, the client area of my display CWnd is not updated, it displays instead a copy of the underlying windows contents.
Debugging (via Remote Desktop) the drawing process does not yield any error in the following procedure I use for drawing the content of my CBitmap *pbMyBitmapToDisplay:
{
CPaintDC dcpaint(this);
CRect rClient;
GetClientRect(&rClient);
CDC dc;
if (!dc.CreateCompatibleDC(&dcpaint)) {
return;
}
CBitmap* pOldBitmap = dc.SelectObject(m_pbMyBitmapToDisplay);
dcpaint.BitBlt(0, 0, rClient.Width(), rClient.Height(), &dc, 0, 0, SRCCOPY);
dc.SelectObject(pOldBitmap);
}
Can someone please give me a clue what is causing the strange display behaviour via Remote Desktop?
Kind regards.
Juri

What function is that code in?

The code is within the OnPaint() message handler of the CWnd.
